Detailed Description

template<class ScalarTypeT>
class vtkBuffer< ScalarTypeT >

internal storage class used by vtkSOADataArrayTemplate, vtkAOSDataArrayTemplate, and others.

vtkBuffer makes it easier to keep data pointers in vtkDataArray subclasses. This is an internal class and not intended for direct use expect when writing new types of vtkDataArray subclasses.
